Description Vitaly 2021-01-20 13:27:56 UTC

Description of problem:
GCC LTO build regression after building mtxclient 0.4.0 both in Rawhide and F33.


Version-Release number of selected component (if applicable):
Rawhide: 11.0.0-0.14.fc34.x86_64
Fedora 33: gcc-10.2.1-9.fc33.x86_64

How reproducible:
Always.

Steps to Reproduce:
1. Rebuild mtxclient package 0.4.0 with LTO enabled (remove %global _lto_cflags %{nil} row and bump Release).
2. Try to build nheko 0.8.0 with this build of the mtxclient package in mock/COPR.

Actual results:
FAILED: nheko

Comment 3 Jakub Jelinek 2021-01-20 15:01:58 UTC

Most likely that is relying on something else instantiating templates for you when that isn't guaranteed.

Comment 4 Jeff Law 2021-01-20 16:32:56 UTC

FWIW, that package was building fine back in late December.  But I basically agree with Jakub, lots of code tends to get template instantiation wrong.  That's where I'd start looking first as well.  I know I fixed a bunch of those kinds of issues in various packages over the last couple years.

Comment 5 Dan Horák 2021-01-20 17:30:36 UTC

FYI https://bugzilla.mozilla.org/show_bug.cgi?id=1556931 shows a fix for a possibly similar issue

Comment 6 Vitaly 2021-01-20 17:40:15 UTC

It builds fine with disabled LTO on all architectures, except the s390x.

Comment 7 Jeff Law 2021-01-20 17:44:57 UTC

ACK.  Both of those are strong signals that this is a template instantiation issue.

Comment 8 Jakub Jelinek 2021-01-20 17:46:27 UTC

In F33 s390x gcc has significantly different inlining heuristics default parameters from other arches, so it inlines a lot more.

Comment 9 Jonathan Wakely 2021-01-20 17:54:22 UTC

This is 100% a template instantiation issue. Instead of repeating that it worked before, look at the code, and fix it.

include/mtxclient/http/client.hpp has a declaration of template member functions mtx::http::Client::put but they are not defined before being instantiated. Either they need to be defined in that header, or an explicit specialization or explicit instantiation needs to be declared, so that the compiler won't try to instantiate it implicitly.

Comment 10 Jonathan Wakely 2021-01-20 17:55:44 UTC

(In reply to Jonathan Wakely from comment #9)
> ... or an explicit
> specialization or explicit instantiation needs to be declared, so that the
> compiler won't try to instantiate it implicitly.

and then in some other file, provide the instantations/specializations that you declared.

The current code is not valid C++, and this is not a GCC bug.

Comment 11 Vitaly 2021-01-20 21:37:15 UTC
